Italy (Sardegna) - Lines with Obscure or Sparse passenger services
This list is based on the timetable in force from 15 December 2019 until 13 June 2020. Table numbers quoted here are from In Treno Tutt'Italia, the official Trenitalia timetable. Standard abbreviations are explained in General Information. Map references relate to the Schweers+Wall Atlante ferroviario d’Italia e Slovenia.
Two useful symbols exist which show the booked route for trains not calling at a station: in the middle of the train column, a vertical bar "|" means that the train passes through the station without stopping, whereas a dot "." means that the train does not pass through that station but instead takes a different route.

Ferrovie della Sardegna obscure services
Limited services, marketed as Il Trenino Verde della Sardegna, normally operate over the following Ferrovie della Sardegna lines during the summer. There are also occasional public excursions at other times. Details are shown on website www.treninoverde.com, but it should be noted that these may vary in practice, particularly if there are insufficient advance bookings. It is also possible to charter trains.
Proposals to close all lines which do not have year-round passenger traffic have been dropped in favour of plans to rehabilitate them. Traffic was suspended from 24 June 2016 between Laconi and Sorgono and between Seui and Arbatax, because of the poor condition of some bridges. The lines to Sorgono and between Gairo and Arbatax re-opened for the 2017 season, but Seui to Gairo remained closed.
Services in 2018 were cut back somewhat and it was announced that there will only be a limited service on one line, thought to be Palau to Tempio, in 2019. This was said to be because of renovation work taking place on other lines. No timetable was available by the start of the normal operating season in mid-June 2019 and there have been reports of legal difficulties preventing any service being operated. By November 2019 there were no timetables posted for any line, only lists of how long it should take to travel between each station.
The timetable for 2018 is as entered below, but is no guide as to what service, if any, operated in 2019 or may do so in 2020.
Palau - Tempio
This is the 2018 Timetable as the website section for this line states no trains operated in 2019 but are planned for 2020.
|D||MWFO||09:00 Palau - Tempio|
|D||TWFSuO||16:00 Tempio - Palau|
Bosa Marina - Sindia
This is the 2018 Timetable as by November 2019 the website section for this line states trains did not operate between Macomer and Sindia in 2019 but are planned for 2020.
|D||SO||15:30 Bosa Marina - Sindia|
Mandas - Laconi
These are the 2018 timings as the website section for this line confirms Laconi to Sorgono was closed in 2019 but a service is planned in 2020
|D||SuO||09:00 Mandas - Laconi|
|D||SuO||17:00 Laconi - Mandas|
Mandas - Sadali
As at November 2019 the website shows timings for two specials on 15 December 2019 running 14km beyond Sadali to Seui. Whether this happened throught 2019 is not known as those below are what ran in 2018. The section of the website for this service states they are planned to resume right through to Arbatax in 2020
|D||MTO||09:00 Mandas - Sadali|
|D||MTO||16:30 Sadali - Mandas|
Arbatax - Gairo
Confusingly only this section of the website claims Gairo to Mandas was closed suggesting no service on IT18/175 in 2019. It does state Arbatax - Gairo should operate in 2020 These are the 2018 timings.
|D||ThFSSuO||08:00 Arbatax - Gairo|
|D||ThFSSuO||16:30 Gairo - Arbatax|
